trifugal drying machine known as the sus-.

pended self-balancing centrifugal drying machine, whichare driven by motors-or belt pullelys through the medium of clutches or coup ings or combinations of clutches or combinations of couplings or combinations of clutches and con hngs.

The motors orrivers are usually supported on-a framework above the centrifugal drying machine, and the same framework may be used to carry the centrifugal drying machine. Hitherto these motors or drivers have been made with the revolving part car ried on a solid s indle with journal bearings at both ends an a thrust bearing, usually at one end.

The improvement consists principally in making the revolving part of the motor, or driver, to, run on a stud supported from above, and with the necessary journal and thrust bearings to keep the revolving part of the motor or driver in proper relative position; The said stud is made hollow which "permits of making considerable improvevolving partof the motor or driver is coupled to the centrifugal drying machine by a flexiiird way the revo ving part of the motor,- or driver, and

started the centrifugal drying machine comes up to full speed at a slower rate than the motor.

De ending upon the kind of motor used and t e manner in which it is to be applied, the hollow of the stud is utilized to pass a revolving spindle through it to work an externally situated governor for regulating the speed of the motor, or a rod may be assed t rough it to connect between an internally situated governor and a throttle valve, trip gear, switch, or other regulating device. Also the hollow of the stud may be used to pass the connecting rod or rods for working the clutches connecting the revolving part of the motor or driver to the centrifugal drying machine, andiri other ways. The revolving part of the motor may be the rotor or armature of an electro motor, the revolving part of a Pelton wheel or it may be a pulley driven by a belt, or the revolving part of any other form of motor or driving apparatus.

' The invention is illustrated in the accompanying drawings in which Figures 1 and 2 .are vertical sections showing two alternative constructions of driving mechanism in which Water is used as the motive power. Figs. 3 and 4 are corresponding views showing res ectively an electric drive and a belt drive.

ig. 5 shows to a smaller scale a centrifugal drying machine fitted with the water motor and connections shown in Fig. 2.

Referring to the annexed drawings, S is the spindle of the centrifugal drying machine, which is carried by the bearing U. The bearing U is carried by the elastic buffer T, which is adapted to control the ratory and-vibrator movements of the spindle S. The buffer T is carried by the casing V, which in turn is supported from the underside of the framing M M R is the brake for stopping the machine.

Referring more particularly to Fig. 1, C is the casing of a P'elton Water motor which is fixed to upper side of the frame M, M. The Pelton wheel B, carries the cups F, which receive the drivin power from water jets (not shown). he wheel B, which, for convenience, may be called the driver, is supported by suitable thrust and journal bearings a, a, upon the stud A, round which it revolves. The stud A is supported from the cover E, of the motor casing- C. D is 'a s indle or rod passing through the bore of t e stud A and conveying motion to the externally situated overnor G, which actuates the gear or mec anism for regulatin the suplply of water to the.

motor, through t e lever and rod K. The driver B is connected to the centrifugal drying machine through the springs L L which form a flexible coupling and allow for the gvrationand vibration of the machine spindle S, and when started the driver B and the centrifugal drying machine rise to full speed to ethe Figs. 2 and 5 the arrangement is similar to that of Fig. 1, exceptfthat the governor G,

is situated within the driver B, and commotor, B is the armature or driver, F are the windin s. The driver B is connected to the cent gal drying machine through a combined cone and centrifugal friction clutch. In drawin W is'one part of a cone clutch carried by t e driver B. W is the other part'of the cone clutch, which runs on the bearing X, and carries the driving arms 1 Q, and which in turn act on the friction b ocks P P of the friction pulley O. I

' The bearing X is carried by the spindle D, supported'from the lever H. In this case the motor runs'continuously, and to start the centrifugal drying machine, the rod-K is released from the catch Z, when the spring Y ulls'the cone W into contact with the cone 2 thus setting in motion the driving arms Q, Q, and frictlon blocks P l? and starting the centrifugal dryin machine. In this construction shown in ig. 4 the driver B is a belt pulley and runs continuousl Connection is made with the centrifu a drying machine through the cone clutch IV flexible coupli L L As in the construction shown in 'g. 3, the cone W is carried by a bearing X on the spindle D. To start the centrifugal drying machine, the rod K is released from the catch Z, and the s ring Y pulls the cone W into contact with t e cone Also the con- W. In this case the cone W slips on the cone W until the centrifugal drying machine has reached full s eed, and the ra idity of the acceleration of t e centrifu al 'ng machine can be regulated by reguIating the strength or leverage of the sprin Y.

For the purpose of this speci cation the revolvin part of the motor or driving pulley is terme the driver, and theconnection between the driver and the centrifugal drying machine is termed the connection.

Having now described my invention what I. claim and desire to secure by Letters Patent of theUnited States is:

1. In a centrifugal drying machine the combination with a driver, a machine s indle, a driving connection between said driver and spindle, a hollow vertical stud supported from above and around which the stud driver revolves, said stud having thrust and journal bearings to keep the driver in its roper relative position, and a rod passing t rou h said stud and operatively associated wit said driving connection.

.2. In a centrifugal drying machine the combination with a driver, a machine spindle, a driving connection between said driver and spindle, a hollow vertical stud supported from above and around which stud the driver revolves, said stud having thrust and journal bearings to keep the driver in its proper rela-- t e speed tive position, means for regulating and acceleration of the machine, and a rod passing through said hollow stud and having an operative connection with said regulating means.

3. In a centrifugal drying machine the combination with a driver, a machine spindle, a hollow vertical stud sup orted from above and around which stud t e driver revolves, said stud having thrust and journal bearings to keep the driver in its proper relative position, a rod passing throu h said stud, and a clutch including one mem er carried by the driver and one member carried by said rod.

.In testimony whereof I have'signed my name to this specification in the presence of two subscribing witnesses, 1
